Description

Technical Field

[0001] This invention relates to the field of canned food production technology, and in particular to a spiral conveyor for automated canned food conveying. Background Technology

[0002] The general automated production process for canned food is as follows: raw material selection → soaking and cleaning → peeling and cutting → hardening → pre-cooking → cooling → sugar syrup preparation → canning → venting and sealing → sterilization → cooling → finished product.

[0003] After canning is completed, the cans are generally sterilized using pasteurization, which involves placing the filled cans in a high-pressure steam boiler or water bath for sterilization. Typically, this requires steaming at around 121°C for about 20-30 minutes to completely kill bacteria and other microorganisms.

[0004] After sterilization, canned goods need to be cooled under a certain pressure in the sterilizer. This is mainly used for high-temperature and high-pressure sterilization, especially for canned goods that are easily deformed or damaged after high-pressure sterilization. After pressurized cooling, they need to be cooled under normal pressure. Normal pressure cooling is mainly used for canned goods sterilized under normal pressure and some canned goods sterilized under high pressure. Canned goods can be cooled in the sterilizer, in a cooling pool, immersed in flowing cooling water, or cooled naturally. After cooling, the water stains on the cans need to be wiped dry before labeling and packaging.

[0005] The existing canned food requires a lot of time to cool under normal pressure. If natural cooling is used, the cooling efficiency is low. Cooling through sterilization tanks or cooling pools requires wiping the water stains on the surface of the cans after cooling, making the cooling process cumbersome. Summary of the Invention

[0006] The purpose of this invention is to provide a spiral conveyor for automated canning, which sprays coolant in the form of mist. The mist is vaporized by the temperature of the can itself, allowing the can to cool down quickly. Then, an air blowing device quickly dries the cooling mist adhering to the surface of the can, preventing the metal lid or metal can from rusting. This invention can quickly cool the can while reducing the cumbersome cooling operations, thereby improving the production efficiency of canning.

[0007] To achieve the above objectives, the present invention provides a spiral conveyor for automated canning, comprising a spiral conveyor body, an atomizing cooling device, and an air blowing device. The spiral conveyor body is used to convey canned goods and includes a first housing, a conveying device, and a support column. The support column is installed inside the conveying device, and the conveying device is installed inside the first housing. The atomizing cooling device is installed on one side of the spiral conveyor body. The support column has multiple spray holes matching the atomizing cooling device, which are used to spray the mist generated by the atomizing cooling device outward. The air blowing device is installed at the tail of the spiral conveyor body and cleans the coolant adhering to the surface of the canned goods by blowing air. The support column has air jet holes matching the air blowing device, and the gas generated by the air blowing device is ejected from the air jet holes. The spray holes and air jet holes are arranged in an array along the outer wall of the support column.

[0008] In one or more embodiments, the conveying device includes a front conveying section, a middle conveying section, and a rear conveying section. A protective cover matching the rear conveying section is fixedly connected to the first housing. The upper end of the protective cover is connected to an exhaust gas treatment device, which is used to treat the gas between the first housing and the protective cover.

[0009] In one or more embodiments, the waste gas treatment equipment includes a fourth housing, a condensing device, and a filtering device. The condensing device and the filtering device are both installed inside the fourth housing. The condensing device is used to condense the gas to be treated, and the filtering device is used to filter the condensed liquid.

[0010] In one or more embodiments, a liquid collection tank is provided at the bottom of the first through hole, and a filter plate matching the liquid collection tank is installed on the first housing. The liquid collection tank is connected to the waste gas treatment equipment.

[0011] In one or more embodiments, the atomizing cooling device includes a second housing, a water pump, and a water outlet pipe. The second housing is filled with coolant for reducing the temperature of the canned goods, and the water pump is used to draw the coolant into the water outlet pipe for atomization and spraying.

[0012] In one or more embodiments, a gas supply pipe is fixedly connected to the gas blowing device, and a heat exchange pipe is fixedly connected to the end of the gas supply pipe away from the gas blowing device. A heating component matching the heat exchange pipe is installed inside the support column, and the heating component is used to heat the gas drawn into the gas blowing device.

[0013] In one or more embodiments, a plurality of sorting devices are provided at the tail end of the spiral conveyor for sorting the canned goods.

[0014] In one or more embodiments, the spiral conveyor further includes a video inspection system for inspecting food inside cans.

[0015] In one or more embodiments, the video detection system includes multiple cameras, an Internet of Things module, and an intelligent analysis module. The multiple cameras are arranged along the spiral direction of the conveying device and are used to photograph the food inside the can.

[0016] In one or more embodiments, the spiral conveyor is provided with a labeling device for labeling cans located on the spiral conveyor.

[0017] Compared with the prior art, the spiral conveyor for automated canning according to the present invention can spray coolant in the form of mist, and vaporize the mist by the temperature of the can itself, so that the can can be cooled down quickly. Then, the cooling mist adhering to the surface of the can is quickly dried by the blowing device, so as to avoid the metal lid or metal can body from rusting. It can cool the can quickly while reducing the cumbersome operation of can cooling, thereby improving the production efficiency of canning. Attached Figure Description

[0032] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0033] Unless otherwise clearly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0034] Refer Figures 1-12 As shown, a spiral conveying device for canned food automatic conveying according to an embodiment of the present invention includes a spiral conveying device main body, an atomizing cooling device 6 and a blowing device 13. The spiral conveying device main body is used for conveying canned food. The atomizing cooling device 6 is installed on one side of the spiral conveying device main body and is matched with the spiral conveying device main body for cooling the canned food transported on the spiral conveying device main body. The blowing device 13 is used for treating the water stains on the outer surface of the can body to avoid the situation that the water stains adhere to the can body and cause the metal parts of the can body to rust.

[0035] Among them, the blowing device 13 is generally an air pump.

[0036] See Figures 1-3 As shown, the spiral conveying device includes a spiral conveying device main body, and the spiral conveying device main body includes a first housing 1, a conveying device 2 and a support column 3. The conveying device 2 is installed inside the first housing 1, the support column 3 is installed inside the conveying device 2, and both ends of the support column 3 are welded and fixed to the first housing 1. A connecting member is fixedly connected between the support column 3 and the conveying device 2, and the connecting member and the support column 3 are used for supporting the conveying device 2. Generally, the connecting member is a metal block and is welded between the support column 3 and the conveying device 2 by welding.

[0037] See Figure 9 As shown, the conveying device 2 conveys in the form of a conveyor belt. The middle part of the conveying device 2 is a fixed plate, the upper and lower ends of the fixed plate are conveyor belts, and the upper end of the conveyor belt is an electromagnet block 4. The electromagnet block 4 can adsorb the canned food. Because the conveying device 2 is spiral, after the electromagnet block 4 adsorbs the canned food, during the process of the canned food being carried by the conveying device 2, the electromagnet block 4 can ensure that the canned food will not be separated from the conveying device 2.

[0038] Specifically, the electromagnet block 4 is an electromagnet and is powered by a wireless power supply method. Thus, it can be ensured that the electromagnet block 4 can rotate with the conveying device 2 on the conveying device 2 without being affected by the cable.

[0039] Among them, the canned food includes a can body and a cover body. Generally, the can body is made of materials such as metal, glass, cardboard, etc., and the cover body is generally a metal cover body. Generally, the electromagnet block 4 adsorbs the metal cover body. If the can body is a metal can body, the electromagnet block 4 can also adsorb the metal can body. It is only necessary to ensure that the canned food will not be separated from the conveying device 2 during the conveying process by the conveying device 2.

[0040] See Figures 1-3As shown in the figure, the conveying device 2 includes a front-section conveying part 201, a middle-section conveying part 202, and a rear-section conveying part 203. The middle-section conveying part 202 is located between the front-section conveying part 201 and the rear-section conveying part 203. Among them, the front-section conveying part 201 is arranged horizontally, the middle-section conveying part 202 is arranged vertically with respect to the horizontal plane, there is a certain angle between the middle-section conveying part 202 and the horizontal plane, and the rear-section conveying part 203 is spiral and is arranged parallel to the front-section conveying part 201. When the canned food has gone through the sterilization process and has been pressure-cooled and needs to be cooled at normal pressure. Through a robotic arm or other transfer devices for canned food, the canned food is placed on the conveying device 2, so that the lid body is adsorbed to the electromagnet block 4. The lid body and the electromagnet block 4 are adsorbed to each other, which can largely ensure the stability of the canned food during transportation on the conveying device 2 and reduce the situation where the canned food detaches from the conveying device 2 during transportation.

[0041] The canned food passes through the front-section conveying part 201, the middle-section conveying part 202, and the rear-section conveying part 203 in sequence. When the canned food is on the middle-section conveying part 202, the canned body and the foodstuff exert pressure between the canned body and the lid body. If the sealing performance between the lid body and the canned body is poor and the lid body is not well sealed on the canned body, the lid body and the canned body will separate, so that the sealing effect between the lid body and the canned body can be preliminarily detected.

[0042] Among them, the angle between the canned food and the horizontal plane can be equal to 90°, less than 90°, or greater than 90°. Generally, when the canned food is on the middle-section conveying part 202, it is better that the angle between the canned food and the horizontal plane is less than 90°. The foodstuff in the canned food moves towards the end away from the lid body, making the force exerted by the canned body and the foodstuff on the connection between the canned body and the lid body greater.

[0043] Among them, the degree of the angle between the canned food and the horizontal plane is determined by the angle set by the middle-section conveying part 202. When the middle-section conveying part 202 is perpendicular to the horizontal plane, the angle between the canned food and the horizontal plane is equal to 90°. When the angle between the middle-section conveying part 202 and the horizontal plane is an acute angle, the angle between the canned food and the horizontal plane is greater than 90°. When the angle between the middle-section conveying part 202 and the horizontal plane is an obtuse angle, the angle between the canned food and the horizontal plane is less than 90°.

[0044] Refer to Figure 2 As shown in the figure, a first through hole 101 is opened on one side of the first housing 1 located at the middle-section conveying part 202. A collection box is installed in the first through hole 101. If the lid body and the canned body are not sealed well and the canned body and the lid body separate, then the canned body will fall into the collection box, which is convenient for storing the canned body that is not sealed well.

[0045] Preferably, multiple weight sensors can also be provided between the electromagnet block 4 and the conveying device 2. The weight sensors are used to weigh the cans adsorbed on the electromagnet block 4. Since the cans are placed on the conveying device 2 at a certain frequency, the multiple weight sensors correspond to the position where a can is located. When the can is on the middle conveying section 202 and the weight sensor detects that the weight of the can decreases from large to small, it is determined that the can body and the lid are separated. At this time, the weight sensor will control the electromagnet block 4 to separate the lid from the electromagnet block 4. That is, after the lid and the can body are separated, both the lid and the can body will fall into the collection box, and the separate lid will not enter the next step.

[0046] After the can passes through the middle conveying section 202, it enters the rear conveying section 203. Since the rear conveying section 203 is spirally arranged, the can will move along the direction set by the rear conveying section 203. During the movement, a certain amount of wind will be generated, and the wind can cool the can to a certain extent.

[0047] See Figures 1-4 As shown, the support column 3 is a hollow support column. The support column 3 includes a front support column 301, a middle support column 302, and a tail support column 303. Blocks are welded between the front support column 301 and the middle support column 302, and between the middle support column 302 and the tail support column 303. The blocks are used to isolate the internal spaces of the front support column 301, the middle support column 302, and the tail support column 303. Multiple spray holes 3011 are provided on the front support column 301. The spray holes 3011 are matched with the atomizing cooling device 6. One end of the atomizing cooling device 6 is installed inside the front support column 301. After the atomizing cooling device 6 is started, water mist will be sprayed outwards from the inside of the front support column 301 through the spray holes 3011. Since the can has just been taken out of the pressure sterilization process and still has a certain temperature, the sprayed water mist adheres to the outer surface of the can, and the heat of the can evaporates the water mist, enabling the can to cool down quickly.

[0048] See Figure 4 Combined with Figure 12 As shown, the atomizing cooling device 6 includes a second housing 602, a water pump 604, and a water outlet pipe 606. The second housing 602 is filled with a coolant for reducing the temperature of the can. The water pump 604 is used to pump the coolant into the water outlet pipe 606 for atomization and spray it onto the outer surface of the can to achieve the cooling effect. Multiple atomizing holes matching the spray holes 3011 are provided on the water outlet pipe 606. Multiple atomizing nozzles matching the atomizing holes are fixedly connected to the water outlet pipe 606. That is, the liquid in the second housing 602 is pumped into the water outlet pipe 606 by the water pump 604 and sprayed out through the atomizing nozzles. The sprayed water mist adheres to the outer surface of the can, and the temperature of the can itself drops as the water mist vaporizes, so as to achieve the effect of rapid cooling.

[0049] The water outlet pipe 606 is provided with multiple atomizing nozzles from left to right. Preferably, the amount of the coolant ejected by the atomizing nozzles on the left side is different from that on the right side. The coolant ejected by the atomizing nozzles on the left side contacts the canned food first, and a small amount of spray can be used. The atomizing nozzles on the right side eject a larger amount of coolant. This avoids the canned food suddenly contacting a large amount of coolant, thereby avoiding the explosion of the canned food caused by the thermal expansion and contraction of the罐体.

[0050] Specifically, as shown in Figure 12 As shown, a sealing cover 601 is installed at the upper end of the second housing 602. After the sealing cover 601 is opened, coolant can be added to the second housing 602. A third housing 603 is also fixedly connected inside the second housing 602, and the water pump 604 is installed inside the third housing 603. The third housing 603 is a sealed box housing. The third housing 603 contacts the coolant to prevent the coolant from entering the third housing 603 and causing the water pump 604 to take in water. By providing a water inlet pipe 605 and a water pump 604 in the second housing 602, even if the water pump 604 is used for a long time, the temperature of the water pump 604 can be effectively reduced by the coolant, enabling the water pump 604 to operate for a long time.

[0051] Among them, a first sealing cover is clamped at the upper end of the third housing 603, and the first sealing cover seals the water pump 604 inside the third housing 603. The water pump 604 can be repaired and maintained by removing the first sealing cover.

[0052] Among them, a water inlet pipe 605 is fixedly connected to the water pump 604 by threads. The water inlet pipe 605 contacts the coolant in the second housing 602. The coolant enters the water pump 604 from the water inlet pipe 605 and then enters the water outlet pipe 606 from the water pump 604. The coolant then sprays onto the surface of the canned food through the atomizing holes and the spraying holes 3011 of the water outlet pipe 606.

[0053] Generally, the coolant is water, and the water needs to be chlorinated, with residual available chlorine of 1 - 3 ppm in the water to prevent the canned food from being secondarily contaminated by the coolant after sterilization.

[0054] As shown in Figures 1-3 As shown, a protective cover 5 is also rotatably connected to the main body of the spiral conveying device. The protective cover 5 covers the upper end of the first housing 1, sealing the rear conveying part 203 inside the protective cover 5 and the first housing 1. That is, the first housing 1 and the protective cover 5 form a closed space, and the rear conveying part 203 is installed in the closed space formed by the first housing 1 and the protective cover 5. That is, the support column 3 is also sealed between the first housing 1 and the protective cover 5, and the coolant ejected from the atomizing cooling device 6 is not likely to flow to the outside of the main body of the spiral conveying device. An exhaust gas treatment device 10 is connected to the protective cover 5, and the exhaust gas treatment device 10 can treat the coolant between the first housing 1 and the protective cover 5.

[0055] Among them, an observation port 501 is provided on the protective cover 5. Through the observation port 501, the situation of the cans on the rear conveyor section 203, as well as the operation of the atomizing cooling device 6 and the blowing device 13, can be observed.

[0056] Specifically, since the coolant ejected by the atomizing cooling device 6 contacts the cans in the form of mist, the cans vaporize the water mist through their own temperature. Since the coolant contains certain disinfection substances, to prevent the outflow of the disinfection substances from affecting people, the vaporized mist is processed by the waste gas treatment device 10.

[0057] See Figure 3 As shown, the waste gas treatment device 10 includes a fourth housing 1001, a condensation device 1004 and a filtration device 1005. The condensation device 1004 and the filtration device 1005 are both installed inside the fourth housing 1001. The condensation device 1004 is used to condense the gas to be treated, and the filtration device 1005 is used to filter the condensed liquid. An intake pipe 1002 is connected to the condensation device 1004. The end of the intake pipe 1002 away from the condensation device 1004 is connected to the protective cover 5. Through the cooperation of the intake pipe 1002 and the condensation device 1004, the water vapor between the first housing 1 and the protective cover 5 can be pumped into the condensation device 1004 for condensation. After condensation, a first liquid is obtained, and the first liquid is transported to the filtration device 1005 for filtration. The water after filtration is transported back into the atomizing cooling device 6 again.

[0058] Preferably, multiple branch pipes can be installed at the end of the intake pipe 1002 close to the protective cover 5. The branch pipes are sequentially installed on the upper end of the protective cover 5. The multiple branch pipes are used to extract the water vapor in different areas. A detection device can be installed on the branch pipes. When the detection device detects that there is more water vapor in the current branch pipe, the extraction power of the current branch pipe can be adjusted.

[0059] Specifically, the first liquid contains a certain amount of disinfection substances. The filtration device 1005 can filter the disinfection substances to obtain a second liquid, and the second liquid is relatively pure water.

[0060] Among them, see Figure 10 As shown, a connecting pipe 1006 is installed between the condensation device 1004 and the filtration device 1005. The connecting pipe 1006 connects the condensation device 1004 and the filtration device 1005. The first liquid enters the filtration device 1005 through the connecting pipe 1006. An exhaust pipe 1003 is installed at the lower end of the filtration device 1005. The exhaust pipe 1003 is connected to the atomizing cooling device 6, and the second liquid enters the atomizing cooling device 6 through the exhaust pipe 1003.

[0061] See Figures 4-5As shown, a liquid collecting groove 103 is provided at the bottom of the first through hole 101. The liquid collecting groove 103 is used to collect water droplets generated by some atomized cooling liquids. A filter plate 104 matching the liquid collecting groove 103 is installed on the first housing 1. The filter plate 104 can filter some particulate impurities. The liquid collecting groove 103 is connected to the waste gas treatment device 10. That is, the waste gas treatment device 10 can pump the liquid in the liquid collecting groove 103 into the waste gas treatment device 10 for treatment.

[0062] Since the second liquid delivered by the waste gas treatment device 10 to the atomized cooling device 6 is pure water, when it is mixed with the coolant containing chlorine in the atomized cooling device 6, the chlorine content in the coolant will be reduced. Therefore, a chlorine supplement device 7 is placed at the upper end of the atomized cooling device 6. The chlorine supplement device 7 is used to detect the chlorine content of the coolant in the atomized cooling device 6 and can also supplement chlorine according to the detected chlorine content.

[0063] Specifically, refer to Figure 3 As shown, the chlorine supplement device 7 includes a chlorine tank and a chlorine content detector. The chlorine content detector is located inside the atomized cooling device 6 and is used to detect the chlorine content of the coolant. When the chlorine content detector detects that the chlorine content of the coolant is too low, it will control the chlorine tank to supplement a matching amount of chlorine into the atomized cooling device 6, making the chlorine in the coolant within the normal range.

[0064] Refer to Figures 1-6 As shown, a blowing device 13 is installed at the tail of the spiral conveying device main body. The blowing device 13 cleans the coolant adhering to the outer surface of the can by blowing. A heating component matching the blowing device 13 is installed inside the tail section support column 303. The heating component can heat the gas blown out by the blowing device 13 and quickly dry the water vapor on the surface of the can.

[0065] Specifically, a plurality of air spray holes 3021 are provided on the middle section support column 302, and the gas inhaled by the blowing device 13 is ejected from the air spray holes 3021. Refer to Figure 1 As shown, an air delivery pipe 1031 is connected to the blowing device 13. A heat exchange pipe 1302 is installed at one end of the air delivery pipe 1031 away from the blowing device 13. The heat exchange pipe 1302 is the same as the air delivery pipe 1301. The heat exchange pipe 1302 is matched with the heating component. The heat exchange pipe 1302 is spiral and is sleeved on the heating component. When air passes through the heat exchange pipe 1302, the air is heated and finally blown onto the can to dry the residual coolant on the surface of the can.

[0066] Refer to Figure 6As shown, the heating component includes a heating part 11 and a lead-out rod 12. The heating part 11 is used to heat the lead-out rod 12. The lead-out rod 12 is located inside the middle-section support column 302. The heating part 11 is in the shape of a long strip, and the heat exchange tube 1302 is sleeved on the heating part 11. The heating part 11 is located inside the tail-section support column 303 and is used to heat the lead-out rod 12, and then the lead-out rod 12 heats the air.

[0067] Preferably, an air filtering device can also be provided on the air delivery pipe 1301 to filter the air inhaled by the air blowing device 13, so as to avoid the situation that dust and other impurities in the air are blown onto the surface of the canned food, which affects the quality of the canned food.

[0068] See Figure 7 As shown, the spray holes 3011 and the air spray holes 3021 are arranged in an array along the outer wall of the support column 3. Since the rear-end conveying part 203 is spiral, the spray holes 3011 and the air spray holes 3021 are matched with the rear-end conveying part 203. When the canned food moves on the rear-end conveying part 203, the canned food can contact a plurality of spray holes 3011 and air spray holes 3021, so that the canned food can be processed in multiple directions.

[0069] See Figures 1-6 As shown, a plurality of sorting devices 9 are provided at the tail end of the spiral conveying device. The plurality of sorting devices 9 are used to sort the canned food. When the canned food is at the tail end of the spiral conveying device, the electromagnet block 4 releases the adsorption to drop the canned food from the spiral conveying device, and the canned food falls from the spiral conveying device onto the sorting device 9, and then the sorting device 9 transports the canned food to the packing place. By providing a plurality of sorting devices 9, one spiral conveying device can correspond to multiple packing workstations.

[0070] See Figure 2 As shown, a second through hole 102 is formed in the first housing 1. The number of the second through holes 102 is generally six. Every three second through holes 102 form a group, and the second through holes 102 in a group are arranged oppositely. Different sorting devices 9 are installed in the oppositely arranged second through holes 102. The different sorting devices 9 are used to transport the canned food to different positions.

[0071] See Figures 1-3 As shown, a labeling device 8 is installed on the spiral conveying device. The labeling device 8 is used to label the罐体 located on the spiral conveying device. The labeling device 8 is generally installed at the rear end of the middle-section support column 302 and is used to label the canned food after drying.

[0072] See Figure 8As shown, the labeling device 8 includes a pair of mounting brackets 803, a first winding roller 801, a second winding roller 802, and a transfer roller 804. The mounting brackets 803 are welded and fixed to one side of the first housing 1. A labeling groove is provided between the first housing 1 and the protective cover 5 for the installation of the transfer roller 804. The first winding roller 801 and the second winding roller 802 are both rotatably connected between the pair of mounting brackets 803, and the position where the transfer roller 804 is installed matches the can body.

[0073] Specifically, a mounting plate 8031 is welded to one side of the mounting bracket 803. An electric motor 806 matching the second winding roller 802 is placed on the mounting plate 8031, and the second winding roller 802 is driven by the electric motor 806. A label paper 805 is sleeved on the first winding roller 801. The label paper 805 is in a roll form. The inner wall of the label paper 805 contacts the first winding roller 801. One end of the label paper 805 is bonded to the second winding roller 802. During the rotation of the second winding roller 802, the label paper 805 located on the first winding roller 801 is wound around the second winding roller 802.

[0074] Refer Figure 11 As shown, S1 is the can body. The transfer roller 804 can separate the label and the backing paper. When the can moves on the rear-end conveying part 203, the can body and the label will come into contact, thereby enabling labeling. Of course, after labeling, the label attached to the can body can also be fitted through a robotic arm. Other labeling devices can also be used in cooperation with the conveying device 2 to perform labeling operations on the cans.

[0075] The spiral conveying device further includes a video detection system for detecting the food inside the can. Specifically, the video detection system includes multiple cameras, an Internet of Things module, and an intelligent analysis module. The multiple cameras are arranged along the spiral direction of the conveying device 2. The multiple cameras are used to photograph the ingredients inside the can, and the multiple cameras enable the ingredients inside the can to be photographed without dead angles.

[0076] The photographed video is transmitted to the intelligent analysis module through the Internet of Things module. The intelligent analysis module determines the quality of the ingredients inside the can by analyzing the color of the ingredients. For example, when the ingredients are cooked, their color is darker; when they are not cooked, their color is lighter. The quality of the can is determined by judging the color of the ingredients. The cans determined to be bad by the video detection system are conveyed to the re-inspection area through the sorting device 9 and then re-inspected manually.

[0077] Among them, the multiple cameras are generally installed near the middle support column 302. There is no coolant near the middle support column 302, which can avoid the situation that the coolant adheres to the camera and affects normal shooting.

[0078] When using the spiral conveyor, cans are first placed on the front conveyor section 201. The front conveyor section 201 transports the cans to the middle conveyor section 202, which is vertically aligned with the horizontal plane, resulting in an angle between the cans and the middle conveyor section 202. The cans exert pressure on the lids. If the can and lid are not properly sealed, the can will detach from the lid. After the can detaches, a weight sensor causes the lid to detach along with the can, ultimately entering the collection box for collection. Once the collection box is full, the cans, lids, and food inside can be cleaned collectively.

[0079] After passing through the intermediate conveyor section 202, the canned goods are transported to the rear conveyor section 203. The cans move along the rear conveyor section 203, with the support column 3 located at the center of gravity. The front support column 301, in conjunction with the atomizing cooling device 6, sprays coolant onto the surface of the cans. The coolant is sprayed as a mist onto the surface of the cans. Even after pressurization and cooling, the cans still retain a certain temperature. The coolant mist adhering to the surface of the cans is vaporized by the cans' own temperature, achieving a rapid cooling effect. Because the rear conveyor section 203 is spiral-shaped, the cans receive omnidirectional spraying as they move along it.

[0080] After the coolant mist is dried by the can, it will form water vapor. The water vapor is extracted by the exhaust gas treatment equipment 10, and after treatment, it is transported back to the interior of the atomizing cooling equipment 6 for secondary use.

[0081] The chlorine replenishment device 7 installed on the atomizing cooling device 6 can monitor the chlorine content in the atomizing cooling device 6 in real time. If the chlorine content is too low, the chlorine replenishment device 7 can add the corresponding amount of chlorine to the coolant in the atomizing cooling device 6.

[0082] When the can is located at the middle support column 302, the air blowing device 13 and the heating component work together to spray hot air out of the air jet 3021. The hot air dries the residual coolant on the can, preventing the metal cap and can from rusting due to insufficient coolant drying. Drying also facilitates labeling. The labeling device 8 can label the can after it has dried. After labeling, the can moves to a position close to the sorting device 9, the electromagnet block 4 loses its attraction to the cap, and the can falls onto the sorting device 9. It is then conveyed to the packaging area for packaging. There are multiple sorting devices 9, each corresponding to a different packaging station.

[0083] As the canned food moves on the rear conveyor 203, the video inspection system also inspects the food inside the can. It judges the quality of the food by judging its color. If it is determined that the food inside the can is spoiled or not fully cooked, the problematic can is transported to the re-inspection station by one of the sorting devices 9 for manual re-inspection.
